When you're standing outside your own front door, it's easy to forget that the person who shows up to open it has no way of knowing you live there. So a residential locksmith will ask for ID and some proof of residence first.
Below is a plain rundown of your options, which documents work as proof, and what to do when your ID and your paperwork are both locked inside with your keys.
Your options, from cheapest to most involved
| Option | Works best when | Watch out for |
|---|---|---|
| Spare key from a family member or neighbor | Someone nearby has a copy | Spares hidden outside can be found by others too |
| Landlord or property manager | You rent and they keep keys | Office hours; some charge an after-hours fee |
| Another unlocked door | A side or garage entry was left open | Only use doors, never climb in |
| Residential locksmith | No spare is reachable | Have ID and proof of address ready |
| Lock change or rekey after entry | Keys were lost, not just locked inside | Decide before the tech leaves |
If the keys are simply on the kitchen counter, opening the door is all you need. If you have no idea where they went, the job usually turns into an entry plus a lock rekey so that whoever finds them can't use them.
What counts as proof of residence
The goal is simple: connect you, by name, to that address. A tech usually wants a photo ID and one document that shows the same name at the same address.
Usually enough on its own
- A driver's license or state ID that shows this address.
Pair with a photo ID if your ID shows an old address
- A current lease or rental agreement with your name on it.
- A recent utility, internet or phone bill mailed to the home.
- Property tax paperwork or a mortgage statement.
- Vehicle registration or insurance card listing the address.
- Mail addressed to you at the home, ideally from a bank or agency.
A bill or statement on your phone can work too. Pull it up while you still have battery, and screenshot it so you're not relying on a signal.
When your ID is locked inside too
This happens a lot: wallet, keys and purse all on the same table. It's solvable, it just takes another step.
- Tell the dispatcher up front that your ID is inside. It changes how the visit goes.
- Ask a neighbor who knows you to stay with you while the door is opened.
- Once the door is open, the tech will usually go in with you to retrieve the ID before finishing the job.
- Show the ID and a piece of mail from inside so the tech can match the name to the address.
A careful locksmith won't skip this step, even if it feels awkward at the time. It's the same check that keeps a stranger from getting a locksmith to open your house while you're away.
Renters: the landlord question
If you rent, check your lease before you call anyone. Some leases say the tenant can't change or rekey locks without permission, and some landlords want a copy of any new key.
- Call the property manager first if they keep a key and answer after hours.
- If they can't come, a locksmith can open the door with your lease and ID.
- Don't swap the lock on a rental without checking the lease, unless the law gives you that right in your situation.
California does give certain tenants a specific right to lock changes. Civil Code 1941.5 applies when a tenant holds certain court orders or a police report; we explain it in our guide on when to change your locks.
How a locksmith opens a house door
The goal on a lockout is non-destructive entry: opening the door without damaging the lock, the door or the frame. The method depends on what's on the door.
- Knob or lever lock only: often the simplest to open without damage.
- Deadbolt thrown: takes more time and skill, since there's no spring latch to work with.
- Smart lock with a dead battery: the way in depends on the model, so give the brand and model name on the call if you know it.
- Broken key in the lock: the piece usually needs extracting first.
Drilling is a last resort, not a starting point. If a tech wants to drill right away on a standard lock, ask why.

Climbing through windows is how people get hurt during lockouts. Sliding a card into the latch can bend the strike or damage the weatherstrip, and it doesn't work on a deadbolt at all.
Make the next lockout less likely
- Give a spare to a neighbor or relative you trust instead of hiding one outside.
- Consider a keypad deadbolt so a code gets you in; see our smart lock installation options.
- Keep a photo of a utility bill in your phone's favorites album.
- If you've lost track of how many copies exist, a rekey resets that count to zero.

Frequently asked questions
Can a locksmith open my house without ID?
Expect the tech to ask for a photo ID and proof that you live there. If your ID is inside, say so on the call; the tech can usually enter with you, then check your ID and mail before finishing.
Will opening my door damage the lock?
In most cases, no. Non-destructive entry is the normal starting point. Drilling is reserved for locks that can't be opened any other way, and the tech should explain why before doing it.
I rent. Can I call a locksmith myself?
Yes, you can call a locksmith to get back in. Check your lease before changing or rekeying the lock, since many leases require the landlord's permission or a copy of the new key.
What if my driver's license shows my old address?
Bring a second document that shows your name at the current address, such as a lease, a utility bill or bank mail. Showing it on your phone usually works too.
